poke first one , i dont like wii emulation on batocera cause controls isues, but gamecube yes is working very good 1080 resolution .
but i´ve tried some wii isos on the 5.19 was working greate at 1080 .
i have 16 gb ram and fx8350 processor 4.0 ghz . works all greate offcoarse respecting the compatibilities list .
for example wii call of dutty black oops was running very poor instead tale of symphonia was working like a charm .
